Are all the phones that works with T-Mobile can be used by Cinguar? I am planning to switch from T-mobile to Cingular so I would like to check it out. Is Cingular using GSM 1900 ?

Thanks..

Yes Cingular uses GSM 1900 but they also use GSM 850 so it'd be very very wise to get a phone that supports both GSM 850 and 1900.

WELCOME TO CINGULAR!!! 😁

In theory you T-Mobile phone WILL work on Cingular. There are a few potential issues that you may have to deal with though . . .

1. T-Mobile (like Cingular) puts subsidy locks on their phones so that they will only run on their network. You will have to get this disabled. If you've been a T-Mobile customer for 90 days or longer and are up to date on all of your billing (no suspension due to nonpayment, etc.), you can get the unlock code from T-Mobile. They are fairly lenient about giving them out.

2. If you are cancelling early, you may be required to return your phone to the store where you got it (depending on the store's policy and how far you are in your contract - if you still are under contract, that is 😁 ).

Thank you very much for your opinions.

My mobile phone is Sharp GX-32, which works under both GSM 850/1900 mHz. Since most of the mobile phones do not work under GSM850 mHz, I would like to know if Cingular Network works fine under GSM1900 mHz in the case that I buy a new phone that works for GSM 900/1800/1900 mHz.

As you mentioned that Cingular uses the 850 mhz band in a lot of places now, do you know what band Cingular is using in New York City?

Besides, how would I use MMS service with my mobile phone if I switch to Cingular network. Can I manually set the configuration myself n order to use MMS?

Thanks again for all of your advises.

ok , do not buy a phone that does not have the 850 band in it ! i repeat do not do it ! if you are coming to cingular get and 850/1900 band phone !you wont have good penetration in buildings and just not very good signal over all thats why t-mo is starting to use 850 their signal sucks! nyny is 850/1900 but to get service in the buildings you Nedi 850!
as far as mms do you have tmo's mms settings on you phone now ? we have media mall att has mmode . I dont know what tmo has but you would at least need to have an unbranded unlocked phone to get it to completely work
(or get a cingular phone ) hope this helps !
